Removing subtitles from lectures, tutorials and screen recordings

Updated November 5, 2026 · Peelframe

Lectures, software tutorials and screen recordings have plenty of text in the picture itself: slide titles, code, tables and menu names are all text. The point is to remove only the subtitles and leave everything else. This is the method for tidying up subtitles on your own lecture or recording, or removing the original subtitles before adding them in another language.

First: are the subtitles burned in?

If you added the subtitles in a recording or editing program, the cleanest fix is to turn the subtitle track off in the original project and export again. If they can be switched off in the player, there is nothing to remove. Soft vs hard subtitles explains how to tell. Use the method below when you have no original and the subtitles are part of the picture.

Why 'Select an area' is better than automatic removal here

Remove subtitles automatically finds text in the picture and removes what looks like subtitles. That is convenient for ordinary videos, but on a lecture screen a sentence at the bottom of a slide or a line of code can look like a subtitle too. For lectures and recordings, Select an area and mark only where the subtitles appear.

1. Draw the area around the subtitle position only

1. Pause on a scene with a subtitle and draw the area so the longest subtitle fits inside.
2. Choose Subtitle text · when visible. It looks only for subtitle letters inside the area and leaves frames without subtitles untouched.
3. Check that the area does not overlap slide text or code. Text in the overlapping part may be removed along with the subtitle.

2. Split the area where slides come close

When the screen layout changes partway through, the subtitle may come close to slide text in some sections. Rather than one large area, use several.

• You can make up to 4 areas, each with its own start and end time.
• For example, the very bottom from 0 to 40 seconds, and a little higher after 40 seconds: split the areas where the subtitle position changes.
• Where slide text sits right above the subtitle, bring the top edge of the area down to just above the subtitle.

3. If there is a bar or box behind the subtitles

If there is a semi-transparent black bar or a coloured box behind the subtitles, Subtitle text · when visible finds and removes the bar as well. If the bar stays in the same place for the whole video, even when there is no subtitle, Whole fixed overlay · selected time removes the whole area for that time and gives a cleaner result.

4. What to check in the result

• Slide text is intact: make sure slide text, code and tables near the subtitles were not removed or blurred.
• Subtitles over code or tables: where a subtitle covered code or a table, the AI draws that area again from its surroundings. It cannot bring back the hidden text itself, so if the code must be readable, record that screen again.
• Plain backgrounds: subtitles over white slides or solid backgrounds usually come off without a trace.

5. Split long lectures

One video can be up to 3 minutes, 1080p and 120 MB. Split longer lectures into 2-3 minute parts in an editing program, process each one, and join them again. Cut where a sentence ends or a slide changes, and the joins will not show. Formats and limits are covered in supported formats.

To finish

Lectures and recordings often have simple backgrounds, so once the subtitle area is right the result tends to be clean. Use this only on your own lectures or material you have permission to use, and do not repost other people's lectures with the subtitles removed.
